Hey guys,

I'm looking for some ideas for an auxiliary fuse box, something with 3 or 4 fused circuits, with about a 50 or 60-amp input capacity but higher is fine too. Outputs would be a 30A and a 10A circuit for now. What I am looking for is something that is compact and accepts blade-style fuses, all I have found so far are the high end audio style that are massive and use tubular fuses. Ideally, it would have a cover to keep things clean but it does not have to be weatherproof per se.

Any ideas? Thanks!

 

I would get something like one of the blocks from Painless Wiring -

Fuse Blocks | Painless Performance

I had one a long time ago, it was really well made with quality wiring. The nice thing is the built-in relay on some of them so you can have hot power and switched power super easy. Run one power wire to the fuse block and one to the ignition switch and there you go.

Thanks Dale, that looks like a quality piece.

The 3 circuit box is just about exactly what I am looking for, would prefer to not have the relay to avoid the need to run a trigger wire to it though.

 

Whether you need a relay or not really depends on what you plan to power with it and whether those devices already have relays. You don't want to power a fuse box off your battery that sends constant power to a bunch of devices that don't know how to turn themselves off. What are you going to use this for?


FYI, a quick search on Amazon comes up with some decent options that fit exactly what you want (if you truly don't need relays). Keywords: fuse box automotive

 

I'll check what they have to see if there is something that will carry the amps, thanks.

 

Not to thread jack. I've got a 3 circuit ignition hot I'm going to be installing, and I was wondering how to ground our the ground terminal if I'm mounting it in the interior to the plastic trim?

 

There are some cheap ones on Amazon like this:

 

I added a watertight Bussman fuse/relay box that is buildable to your needs. It is small, has a wartertight cover, and holds 5 mini relays and I think 8 mini blade fuses. I mounted it on the frame under the hood on the passenger side where the stock airbox once lived. Ran power from the battery or if needed you can run ignition on from a source under the dash on the driver's size. I actually even added a second Bussman under the front bumper for other needs that was two rows of mini fuses with separate feeds, one battery power and the other ignition on power. Work great.

+1 for Eaton Bussmann fuse box. It's super nice and you can customize it how you want. I'm adding one in my trunk for my 3 fuel pumps. You can have them in different configurations 3, 4, 5 relays, etc.

 

The Eaton Bussmann looks perfect for my project. Thanks for the tip!

 

Also check out www.littlefuse.com for some great products. They make modular fuse and component holders (POWR-BLOK) and sealed boxes (Hard Wired PDM) that can be wired any way you want. If you find something you like on their site, you can order from Mouser or any bulk electronics supply company or search eBay for the part numbers and you'll find packages that have what you need for boxes containing multiple relays and fuses. Then you just need a decent wire crimper.
